To all 1071 am. it may concern: I

Be it knownthat I, WALTER A. Cnownus,

i a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Machines for Making Storage- Battery Plates, of which the-fo1lowing is a specification.

My invention relates to anximprovement in machines for making the lead supporting plates for the active material, or material to be rendered active, in a stora e, or secondary battery of the constructionf' dhown and described in my "application for Letters Patent of the United States, Serial No. 779,325, filed concurrently herewitlf'on the 16th day of July, 1913. i v

In the accompanying drawing, Figure 1 shows my improved machine in operation by a View in sectional elevation, the section being taken on line- 1, Fig. 2; Fig. 2 is a sec-' tion on iine 2, Fig. 1; Fig. 3 isa plan section on line 3, Fi 2; Fig. 4 is a plan view of a broken lengt or the lead support made by the machine, and Fig. 5 is an edge-view of the same. r

A. pair of rolls, 6 and 7, are j ournaled, respectiveiy, in upper and lower hearings in the side-posts, 8 and 9, of a frame which is bolted to a bed 10. These rolls are geared together, as shown, and the roll 7 carries on an end of its shaft a belt-pulley for driving it. Each roll-is provided with' annular series of teeth 11, of the rounded and preferably semi-circular or approximately semicircular shape shown, and uniformly spaced apart. These annular series of teeth, of which ten are shown on each roller, though the number may be greater or smaller, are uniformly spaced apart, and the rolls are relatively disposed in their supporting frame to cause the series of teeth about one to enter the spaces between the series of teeth about the other. A guiding stripper 12 extends between the rolls, being rigidly supported at its flaring ends on four posts 13, as shown. This guiding stripper is formed of two spaced sheets of metal of the flaring shape illustrated in Fig. 3, with the sheets relatively close together at one side of the rolisto afford a guide for a thin sheet of iead (of about inch in thickness) fed thereto, and spaced farther apart from near the point of entry of the sheet of lead bctween the'roils to their opposite end. to guide the'sheet, after it has been acted on by the rolls, out of the machine and prevent it from adhering to the teeth of either roll I and foll owing it about in its rotation, thereby acting as a stripper. Where the guidmg-stripper extends between the rolls, it,

contains a series of spaced slots'l i to permit the teeth on the two rolls to coiiperate through them, theseslotsbeing in staggered relation in the upper and lower sheets or-n int; the device 1 v o operate the machine, a sheet of lead, suitable for a support. for the active n1a-v 'terial ofia storage-battery, is fed in any desired continuous length through the relatively-narrow end of the device 12 between.

the rolls which, in rotating, force their teeth into the sheet, cut it and en and itinto interstitial or latticed tubes at the intervals on the sheet of lead corresponding with the spaces between teeth; these tubes projecting on opposite sides of the teeth and being pro vided to receive and hold the active material,

or material to be rendered active, of a stor= age-battery, the filled support thus afi'ording an element of the battery. i

The sheet of lead acted emerges therefrom in the form represented in Figs. 4 and 5, of a series of interstitial or latticed tubes 15 projecting on each sidepf Sit on by the roiis ,the sheet at intervals across which they lates having series of interstitial tubes pros,

jecting atintervals on the opposite plates surfaces, comprising a pair of journaied.

rolls geared together, each rolljbeing pro vided with a series of spaced rings in steer rel ation on the opposite rolls and haw tion to afford a relatively shallow guide at "7" g rounded cutting teeth, the teeth on each =tlie feed-end and a relatively wide guide and .rqll working in the spaces between the rings stripper between and beyond the rolls.
